Just bought a MegChip 2000

With a PLCC puller, the Agnus chip will pop right out. The Megachip will insert easily. Press firmly and make shure it is properly seated and you will be good to go. I did this years ago. As I remember there are two places you can clip the jumper to, one on the 68000 and one on another chip the 68000 lead is connected to. The clip is designed to prevent shorting but a lot of users cut off the clip and solder the wire to the pin. If your soldering skills aren't up to it, don't try it, just use the clip.

BEFORE installing the MegaChip, wrap a nylon wire tie around the Agnus socket and tighten it snug. Do not over tighten. This will help keep the Agnus socket from splitting over time. Do NOT use the clip. Find a "thru-hole" that connects to pin 36 on the Gary chip or pin 48 on the 68000 chip and solder the wire from the MegAChip to this hole. It would be best if you remove the Amiga 2000 motherboard, so that you can solder the wire on the solder-side of the thru-hole.
 
If you do not actually NEED the extra meg of Chip ram, do not bother installing a MegAChip. It does put a lot of stress on the old Agnus socket, and if the socket splits, it is a major repair. So, do not let your ego cause you to damage an otherwise perfect Amiga 2000 motherboard.  In most cases, one meg of chip memory is plenty.

That's really overkill. The clip works fine. The problem would be if the A2000 got moved around a lot. In that case, it would be best to solder the lead to the pin on the 68000. No need to take the MB out. This is the sort of work that was done at the factory a lot to put in last minute engineering changes.

2mb chip ram is a vast improvement and worth installing. Back in the day, the A2000s 1mb chip ram got to be more and more a limitation as software started to be written for 2mb chip ram A3000s and A4000s.
